Receptor-Associated Protein Of The Synapse Recombinant Protein | RAPSN recombinant protein
Recombinant Mouse Receptor-Associated Protein Of The Synapse
Sterile Filtered clear solution.
Introduction: 43 kDa receptor-associated protein of the synapse (RAPSN), is expressed in the postsynaptic membrane of skeletal muscle. RAPSN is essential for the clustering of nicotinic acetylcholine receptors (nAChR). In addition RAPSN self-associates via at least two of its seven tetra-tricopeptide repeats (TPRs). RAPSN interacts with the large intracellular domain of the nAChR a subunit all the way through the hydrophobic surface of the coiled-coil domain. RAPSN modifies trafficking of AChR within the cell. Overexpression inhibits agrin-induced AChR clustering pathway. RAPSN also plays a role in postsynaptic congenital myasthenic syndromes.
NCBI and Uniprot Product Information
Uniprot Description
RAPSN: Thought to play some role in anchoring or stabilizing the nicotinic acetylcholine receptor at synaptic sites. It may link the receptor to the underlying postsynaptic cytoskeleton, possibly by direct association with actin or spectrin. Defects in RAPSN are a cause of congenital myasthenic syndrome with acetylcholine receptor deficiency (CMS-ACHRD). A postsynaptic congenital myasthenic syndrome. Congenital myasthenic syndromes (CMS) are inherited disorders of neuromuscular transmission that stem from mutations in presynaptic, synaptic, or postsynaptic proteins. Defects in RAPSN are the cause of fetal akinesia deformation sequence (FADS); also known as Pena- Shokeir syndrome type 1 or fetal akinesia sequence or arthrogryposis multiplex congenita with pulmonary hypoplasia. FADS is a rare condition characterized by decreased intrauterine fetal movement, congenital limb contractures, pulmonary hypoplasia, polyhydramnios and craniofacial abnormalities. Belongs to the RAPsyn family. 2 isoforms of the human protein are produced by alternative splicing.
